Evening

 

On the way to mot it didn't sound great, possible misfire.

 

Mot tester said left bank was fine emissions on the right bank was jumping around and was difficult to get a steady reading.

 

It still passed.

 

Driving home once over 4000 revs it sound better less lumpy, but the right bank cel came on followed by the right cat. Limped back to garage.

 

The right cat was glowing (under its metal cover).

 

Let it cool for 30mins and limped home without a problem, it felt rough but no cels.

 

Car is a "2003 coupe update".

 

Will it accept obd ?

 

nearest dealer -10 miles.

 

Sensors ?

Coils ?

Cat itself

 

Neither sound cheap ....:

 

Thanks

Glowing cat means there is unburnt fuel going into the cats and burning there. That is usually caused by a bad coil, which is not uncommon on the 02-03. Don't do that anymore until you get it fixed, or bad things will happen, like burning the car to the ground.

Evening,

 

Scanned and it revealed no codes, but with no cels I would expect that.

 

What next ? Do I run it at idle to see if ot would generate a code ?

 

Hopefully without blowing the engine up !!

 

Thanks

There is a reason that unburned petrol is making its way to the cat. I concur with Stimpy - a bad coil or possibly a bad plug would be my guess.

 

If Sevenoaks can't sort it try Mike Pullen at Carrerasport.

If they are original coils, I would just replace all of them with the aftermarket improved versions. As I mentioned before, the 02-03 had problematic coils, which is why they changed them in 04.
